In this research project the possibility of combined forming and joining of sheet- and bulk-metal elements in one process step was investigated. Joining of both parts was realized by a form fit as well as a material bond. In the future the results of these basic studies can be used for application optimized hybrid parts. In this parts sheet metal can be used for part areas with lower mechanical stress and bulk metal elements can be used for heavy-duty part areas. Those hybrid parts can provide good mechanical properties and reduced weight compared to forged parts.
Publications about the project
In this paper the development of the new production technology hybrid forging is described. Hybrid forging combines forming of bulk and sheet metal-elements including joining. Using three model experiments the joining by material bond and by form closure is analyzed. The form closure works like a riveting and the experiments showed good results. But not in every area of the specimen a material bond was present.

In this paper the development of the new production technology hybrid forging is described. Hybrid forging combines forming of bulk and sheet metal-elements including joining. Therefore the classification of hybrid party by material and by the type of the semi-finished product is discussed. In addition, the benefits of hybrid parts are explained. In experimental forging tests with simple geometries a cylindrical bulk part was joined positively with a sheet metal by form closure. A material bond was only partially achieved.
